UNITED STATES WEB M. EDDINS, .OF BARNETT, MISSISSIPPI COMBINATION TRIMMING AND SLAB KICKEB.

Application filed April 28, 1926. Serial No. 105,241.

The object of the invention is to provide a mechanism for use particularly with portable saw mills, so that the trimming of lumber may be readily accomplished and the resultant waste slabs promptly disposed of with a minimum of work on the part of the operator; to provide a construction wherein the kicker drum is directly coupled to the trimming saw to rotate the latter and also to feed the latter to the work; and to provide a construction wherein the feed may be under the control of the operator to effect it and discontinue it when necessary and independent of the rotation of the saw. With this object in view, the invention consists in a construction and combination of parts of which a preferred embodiment is illustrated in the accompanying drawings, wherein:

Figure 1 is a top plan view of the apparatus embodying the invention.

Figure 2 is a side elevational view, there being indicated in dotted lines a foot'control for the feed.

Figure 3 is a longitudinal sectional view on the plane indicated by the line 3-3 of Figure 1. 3

Figure 4; is a transverse verticalsectional view on the plane indicated by the line 4 -4: of Figure 3.

Figure 5 is a detail sectional View on the plane indicated by the line 5--5 of Figure 2. The trimn'iin saw 10 is rotated on its own axis as well as being fed bodily to the work by means of the shaft 11, thelatter carrying the toothed drum 12 designed for the disposition of the waste slabs and being terminally provided with a pulley 14: by means of which it may be belt-driven from an appropriate countershaft. The shaft 11 is journaled, 16, the latter being a lateral extension of the mainframe 17 on, which the saw frame 18 is slidably mounted, the latter traversing the slides 19 of the main frame and being guided in its movement by the straps 20, the latter straddling the side rails of the saw frame.

The mandrel 21 by which the saw is carried is journaled in the saw frame atthe forward end of the latter and between the side rails of the saw frame carries a pulley 22, over which is. trained a driving belt 23, the latter also being trained over a pulley ea carried by the shaft 11 over a tightener pulley 25 and over a rear pulley 26, the latas indicated at15', in a frame 7 ter being carried on a shaft 27 spanning the s de rails of thesaw frame and journaled in appropriate bearings formed therein. The tlghtener pulley 25'is carried by a rock frame 28 pivoted, as at 29, to the main frame and subject to the tension of a contractile spring 30 having one end secured to the rock frame and the other end to the extremity of an eye-bolt 31 mounted in the main frame and provided with an adjusting nut 32 by which the tension of the spring may be regulated and therefore the pull of the tightener pulley. By this construction, motion'on its own axis is communicated to the saw from the shaft 11, this shaft being driven by the pulley 14 and hence rotating the kicker drum simultaneously with the saw.

In operation, the saw is advanced bodily in a direction at right angles to its axis of rotation for the trimming of stock carried by the roller bed which is disposed in the position indicated by the dotted line in Figure 1. The saw, therefore, moves transversely across the roller bedover which the lumber moves as in the conventional practice. The rough ends are trimmed by stopping the lumber on the bed and then advancing the saw frame for the trimming of the lumber, the useless slabs being then manually cast onto the kicker drum 12 and, impinging upon the teeth thereof, are cast to a point remote from the apparatus.

The bodily movement of the saw and saw frame is effected by means of the belt 23 which rotates the saw." On the main frame 17, there is mounted a second" rock frame 33 pivoted to the main frame, as indicated at 34. This rock frame 33 carries at its upper end a friction roller 35 adapted for movement toward and away from the lower run of the belt 23. On the shaft 36 by which the frictionroller 35 is carried, there is mounted a Winding drum 37, this drum being carried on the protruding end ofthe shaft 36 and to it there is connected one terminal of a feed cable 38, the latter traversing the idler sheaves 39 and 40 rotatably mounted on the main frame and disposed respectively adjacent the rear and forward guide straps 20, the feed cable being terminally anchored, as at 4:1, to one of the side bars of the saw frame. The idler sheaves 39 and 40 are simply direction rolls, so that as the drum 37 is rotated, the cable may be reeled thereon and the saw frame bodily advanced to feed the saw to its work. Whether or not the frame Obviously, the application of a, pull on the upper portion of the handdever, \v ll eff fect movement of, the rock frame to,engage the friction roller. 35 with the belt 20, and,

if the shaft 11 be rotated, the saw frame will be advanced as Well as therotationof the saw 10 effected. Means may beprovided for locking the h andlever in, the position here the friction roller is engaged with the belt or inthe position Where the frictionu'oller-is disengaged therefrom bntiinpractice this is not foundto be nccessary or evenadvisable, the operator n'ierely maintaininghis pull on the hand leverduring the movement; of the saWto its Work. When thecuthas been con; cluded, the release of,pressurc on the hand lever. Will permit the saw frame to be returnedto its initial positionwhich is acconj plished by means of weighted? with; which cables 48 are connected, the latter being terminally secured, as at .4-9, to the rear end of the saw frame and trained oversheavcs 50 rotatably mounted. at the rear end of the main frame.

In Figure 2 is, illustrated in dotted lines'a pedal 5l for effecting the movement of the rock frame 33 to engage thefriction roller 35 of the belt. 20. This pedalds; pivotally mounted, as indicated at, 52, andprov i-ded With an upturned cxtension53, theextremity ofWhich extends through an eye 54 in the forward extremity of the link 455. Ohviously, the pressure. upon the pedal 5hwill serve to eifectilongzitudinalmovement of the linkiin the samemanner as is-accomplished by the handlever 412 and therefore constitutes a foot means forv the actuation of the saw feed.
